Signs, Symptoms, and Treatment of Nicotine Overdose

What Is Nicotine?

Nicotine is a highly addictive central nervous system stimulant.1 When ingested, it improves your focus and concentration, accelerates your heart and breathing rate, and increases blood pressure. It is linked to raised alertness, the sensation of euphoria, and a sensation of being relaxed.2

Once in the habit of using nicotine in any form, it is very difficult to stop. According to Medical News Today, it is at least as hard to give up as heroin.

Unlike heroin, however, it is much harder to achieve a lethal dose of nicotine. In fact, it's extremely rare to do so. The vast majority of reported cases of nicotine poisoning or overdose have not been from people using the drug for recreational purposes, but from cases of accidental ingestion of nicotine products (especially for kids), from contact with tobacco leaves, or from its use as a pesticide (which has been outlawed in the United States since 2014).3

That said, it is possible to overdose on nicotine, which for the purposes of this article means ingesting a lethal dose. Cigarettes, gum, patches, and e-liquid containing nicotine could all potentially cause an overdose if taken in large enough amounts. Usually, this is seen in the case of children or pets accidentally ingesting these products.

What most people are more likely to experience is a series of unpleasant side effects that result from ingesting a larger-than-comfortable dosage of nicotine.

Note: You should never drink e-liquid, and never ever combine smoking with patches, gum, or any other combination of nicotine-containing products. Doing so can be very dangerous. For children and pets, accidental ingestion of these items can be very serious. Keep them away and out of reach.

How Much Is Too Much Nicotine?

A likely figure for a lethal dose of nicotine for adults has been estimated to be between 500-1000 mg.4 In contrast, the average U.S. cigarette delivers between one and two mg of nicotine, though this amount differs by brand and type.5 It would take smoking over 100 cigarettes in a short time period to ingest a lethal dose.

You don't have to smoke 100 cigarettes to start feeling sick, however. Even at dosages much, much less than a lethal dose, nicotine can cause some very unpleasant side effects.

Nicotine Sickness (Nic Sick)

Nicotine sickness is not life-threatening, just very unpleasant. Luckily, because it's so unpleasant, it prevents people from continuing to ingest nicotine and reaching toxic doses. Its symptoms often include:

  • Nausea
  • Racing heart
  • Sweating or clamminess
  • Anxiety

The amount of nicotine a person can take without feeling any ill side effects varies drastically due to:

  • Age
  • Weight
  • Gender
  • Prior nicotine usage
  • Whether or not they've eaten recently
  • Other biological and behavioral factors

It can be easy to accidentally take an uncomfortable dose of nicotine if you've started to use it again after a period when you weren't using it, when you're using a new delivery method (i.e. vaping), or if you're trying a new product (like a new cigar or new e-cig liquid).

If you're experiencing nicotine sickness, and unless you've ingested a large amount of nicotine in a highly unusual manner (as in the above scenarios), you're going to be okay. There are some things you can do to help with the discomfort.

  1. Stop taking the product that you're taking the instant that you feel nauseous or otherwise unwell. If you've spilled any e-cig liquid on your hands or body, wash the affected area with soap and water.
  2. Drink several glasses of water—this may help dilute the concentration of nicotine in your body.
  3. Eat sugar—some people swear by eating several spoonfuls of sugar, drinking a Coke, drinking juice, or eating milk chocolate to counteract nicotine sickness. The logic behind this, which seems to be supported by medical evidence as well as anecdotal evidence,6,7 is that nicotine causes a metabolic response that leads to rapidly fluctuating blood sugar levels, which can lead to nausea. Eating sugar helps bring your blood sugar levels back up.
  4. Eat something in general—if you can keep food down, eating something light and easy to digest (like toast, rice, bananas, or an apple) may help ease nausea as well.

The effects can last from between an hour to several hours, though there shouldn't be any lingering side effects after that.

Unfortunately, though cases of nicotine sickness are well-documented by users, it seems this has not been well studied by the medical community. Please be careful with your nicotine use and observe your body carefully, especially when changing products.

Signs and Symptoms of Nicotine Poisoning

Since lethal doses of nicotine for adults is somewhere between 500 and 1000 milligrams, most nicotine poisoning cases occur in rare circumstances, such as in high industrial exposure to the chemical.

As mentioned above, accidental ingestion of high-nicotine products by children and pets is one of the most common causes of nicotine poisoning.8

There are many ways for nicotine to enter the bloodstream, from smoking regularly or vaping e-cigarettes to using chew, patches, or gum. Nicotine can also enter the bloodstream through direct skin contact. Note: Never use nicotine patches other than as directed, and do not combine their use with smoking or other nicotine-containing products. Though this is unlikely to cause any kind of permanent damage, it could result in nicotine sickness.

Nicotine only makes up approximately 0.6–3.0% of dry weight in tobacco, which is the main ingredient of a tobacco cigarette. On average, a cigarette manufactured in the United States contains about 9 mg of nicotine, but this is not the amount of nicotine that is ingested by a smoker. When cigarettes are burned, the smoke is inhaled by the user into the lungs, where the nicotine is absorbed into the bloodstream. The amount of nicotine actually entering the body varies, though it is typically between one and two mg.5

Symptoms of Overdose

Poisoning from nicotine is generally seen in two stages. The first happens within the first 15 minutes to an hour after the poisoning, and the second occurs between 30 minutes and four hours after ingestion.9

1st Stage

  • Nausea
  • Vomiting
  • Abdominal pain
  • Sweating
  • Hypertension
  • Tachycardia, or a dangerously fast heart rate
  • Ataxia, or a lack of muscle coordination that may affect speech, eye movements, and the ability to swallow or walk
  • Headache
  • Dizziness
  • Shaking and tremors
  • Seizures

Some of these are similar to nicotine sickness, though, in the case of a true overdose, they will be more severe.

2nd Stage

  • Bradycardia (slow heart rate)
  • Hypotension (low blood pressure)
  • Central nervous system depression
  • Coma
  • Lethargy
  • Shallow breathing
  • And finally, breathing and respiratory failure

Nicotine Overdose? Call Poison Control!

If you or especially a child has swallowed any kind of tobacco or nicotine product or spilled it on your skin and you suspect a nicotine overdose, call Poison Control at 1-800-222-1222 (U.S.) Have the following information ready when you call:

-Patient's age and weight

-Name of the product

-Amount that was ingested

-When it was ingested

What to Do If You Think You or Someone Else Has Overdosed

For a mild nicotine overdose, follow the steps given above for treating nicotine sickness.

When a nicotine overdose is serious or life-threatening, however, you need to take a few more precautionary measures.9

Call Poison Control (U.S.: 800-222-1222) if you suspect that you or someone, especially a child, has swallowed any kind of tobacco or nicotine product or gotten liquid nicotine in their eye or spilled it on their skin. If you can, have the following information ready when you call:

  • Patient's age and weight
  • Name of the product
  • Amount ingested
  • When it was ingested

If the poisoned person can't wake up, has a seizure, or can't breathe, call 911.

Do not try to make them throw up or give them antacids to settle the stomach. It is okay, however, to offer them water. They'll likely start vomiting on their own.

For nicotine in the eyes, rinse the eyes with warm water for at least 15 minutes. And when it's gotten on the skin, wash the area with warm soap and water.

If You Go to the Emergency Room

In the emergency room, you may receive:10

  • Activated charcoal
  • Medications to control the symptoms
  • A tube through the nose or mouth to wash out the contents of the stomach

If you catch the poisoning in time, the outlook is generally positive with no long-term side effects.

Wishing You Safety and Good Health

All recreational drug use needs careful attention, especially in households with children or pets that could be affected. Please be careful when using nicotine and make sure those around you are safe too.

I think I have nicotine poisoning I threw up and have a fast heart rate and feel like shit and I'm scared someone help

I am a child and I was here to tell my mother and father to stop smoking. Also I was here on this web page to study for school. Thankfully I don't smoke!

Maggie on April 09, 2017:

I have quit smoking for 5 months but can't give up the nicotine lozenges especially when I have alcohol

Jon on February 23, 2017:

I kinda thought I might be having problems from the nicotine I get real bad hot flashes feel like I'm going to get sick hands shake all the time and I feel like my sugar is super low and get real panicky feeling and makes it hard to swallow food when I'm eating I think a can Of chew a day for several months have made it worse time to start trying to quit

Omg on January 12, 2017:

You know, this is making everyone freak out about vaping. For those who see this....DONT STOP VAPING BECAUSE OF THIS ARTICLE. Thats not exactly the cause. First of all if your vaping get educated by a worker or friend who uses mods. Mods are the best way to go because the max mg you should go is 6. And most us 3 or under. So inorder for anything to link to vaping with a mod is vaping litterly 24/7. I understand th is article is trying to educate but i belive its scaring people away of a non lethal thing. If you are vaping and dont know much about it then you shouldint have vaped tell you found out. But this is solid info, but vaping wont lead to OD unless one, your using over say 24 to 30 mg nic, and vaping that non stop.

Rebecca (author) from USA on December 03, 2016:

Thanks for the comment :) Glad it helped.

Rebecca (author) from USA on December 03, 2016:

sounds like detox. People forget how many toxins accumulate in our bodies when we smoke for years and years, the body needs time to recover.

Awesome job on quitting! If it continues you may want to see a doc just to make sure you're not under the weather.

Rebecca (author) from USA on December 03, 2016:

I'm assuming she was drinking at the casino? Sounds more like a hangover to me sorry. The odor could be from a combo of multiple toxins leaving her body. Mood disturbance is more likely from another substance. Good luck to you, sorry to hear she was so rude, that's never fun.

Rebecca (author) from USA on December 03, 2016:

excessive nicotine can cause cardiac arrest or respiratory failure, please don't use both. :(

It's unlikely with the dose you mentioned, but why take the risk?

Rayne on November 13, 2016:

The pixie stix worked wonders! Had a nicotine lozenge with a too high nicotine and an empty stomach. Thanks for the article!

Thanks for your comment Monika, I'm glad to hear you are ok! :)

Monika on September 25, 2016:

Thanks for the article! I just spent 10 hours in hospital on the emergency department because of misuse of the e-cigarette. I dont believe I smoked too much of it , but it was leaking and some of the liquid came in with my mouth, I suffered for 9 hours, whole night of vomiting,confusion,headache,dizziness, and god knows what i else. I can say it was the worst night of my life by far. Eventually I was put under a drop in the hospital and a lot of medication to clear it out of my system. So really just want to say be careful everyone , each person can take in a different amount than another.

Sandy on July 18, 2016:

I know I overdosed on this because I was sure I was dying, heart attack or something like it. I will never touch this thing again not worth the risks.

Lilith on November 14, 2015:

Thank you so much for this article, yesterday I smoked Ambil, mixed with regular tobacco in an attempt to try making something such as Mapacho. The ambil was made from N. Rustica var mohawk. Anyways long story short I had heard about the Curanderos using mapacho and tobacco tea for their voyages and I got interested myself. The ambil I usually eat in the size of two rice grains, assuming the absorption to be more efficient orally (as with tea) I though using one grain of rice worth of ambil with regular tobacco should be OK. Well not really... Ended up taking one toke and then lying in my bed for 3 hours fearing for my life as my heartbeat went up to 200bpm for a shortwhile (10-20min).

The most surprising thing is that it didn`t feel like characteristic nicotine high, as of Thuoc Lao or regular tobacco (N. Tabacum), maybe due to the beta-carbolines.

Anyways, I just wanted to write this as a warning. It`s an efficient poison and can be very interesting but if you`re going to experiment always start really low and be careful. Nicotine poisoning is not fun.

maxmilian michael on October 31, 2015:

i thought real cure of nicotine is the use of phenegan and modicate to recover again but modicate has high risk drwasness which can effect your work even study if any one have any medicayion taste which have low drawseness can conctact me

john on July 01, 2015:

Sorry to hear about the problems you have experienced. I have been vaping for over 3 years, and yes I have had a few headaches before I dropped to 6 or below on nicotine level juice. Now, no more headache or problems (I use about 20-30 ml of juice daily).

However, my friend who has been vaping for 6 months has also explained that he has had some of the same symptoms expressed above. This got us wondering so we did a bit of digging and found this on wikipedia: "Propylene glycol is used as a humectant (E1520), solvent, and preservative in food and for tobacco products, as well as being one of the major ingredients of the "e-liquid" used in electronic cigarettes along with vegetable glycerin. Propylene glycol is also used in various edible items such as coffee-based drinks, liquid sweeteners, ice cream, whipped dairy products and soda.[8][9] Vaporizers used for delivery of pharmaceuticals or personal care products often include propylene glycol among the ingredients.[5] Propylene glycol is used as a solvent in many pharmaceuticals, includingoral, injectable and topical formulations, such as for diazepam and lorazepam which are insoluble in water.[10]'

Come to find out, he is sensitive to the PG in the e-liquid, soda, and ice cream. He still vapes, but has transitioned to high vg juices and a dripper and he problems have seem to fade away. Best part is, he is no longer smoking and feels great. Best of luck to all of u, P.S. stay away from gas station e-juice. Pay for the quality juice.

Dougg on June 15, 2015:

Been vapeing for about 2 years now and got the headaches more than a few times. Now with this new mod, I have had a few chest pains which I'm sure is due to over-vapeing and cloud chasing.

My next move is to lower my nicotine level.

Thanks for the write-up....pretty informative.

SeanGauld on June 07, 2015:

I started using the ECig a number of months ago. I was purchasing the £10 ones. They started leaking in my bag and pocket so I threw it away, had another one, threw that one away too. I was just as good as done with ECigs. Went back on to Cigarettes.

My dad handed me this Blu Ecig. I tried it and proven to be affective, No leaking, no trouble. I'm still using it on and off but mainly on. The date is now 07 June 2015, been without a cigharette for 3 days now. I know it's early days but I cycle alot and can Deffo' feel it.

I can sit there and puff away and make myself ill but hey, it's doing me good.

I don't know where I'd be without the Ecigs. FAB bit of equipment.

ncyp13 on June 06, 2015:

useful informative nice work

Daniel Washington from United States on April 06, 2015:

Thank you for sharing the symptoms and treatments of nicotine. I was actually looking for the informative stuff like this. I would definitely recommend this hub to someone in need or lacks knowledge about the nicotine. Thanks again!

Frank on March 22, 2015:

Friend gave me 23 ml bottle of liquid for my vape. I'm 18 and I Smoked too much of it today and my body went numb on the spot. I also got really dizzy too and my anxiety kicked in. Seriously thought I was dying even though I knew it was impossible. Good luck to anyone who has to go through that too, scared me really badly.

Fernando on February 28, 2015:

Your article was very helpful, I enjoy vaping but suffered dizziness and fatigue. I guess I had hit the mod too much. Your sugar under the tongue proved very useful.

Ashton on February 22, 2015:

This helps a lot. I didn't even know overdosing on nicotine was a thing. This happened to me when I was smoking hookah for 3 hours straight. I passed out three times, was having severe muscle spasms, and throwing up. This is a real thing.

Rebecca (author) from USA on February 06, 2015:

Hi jeje,

Thanks for your comment. Stress can do really crazy things. It doesn't seem to me that you are having these issues from vaping. Do you drink? Or have you recently quit drinking?

jeje on February 06, 2015:

This is very interesting. I've been vaping for over a year and been working in a vapor shop for just as long. All these symptoms chalk up to what's been going on the past month. Ive been having seizures, super anxiety, shakes, lack of sleep and throwing up about 4 times a day. I don't understand why the symptoms would just start now though? Me and my doctors visits have chalked it up to the amount of major stress I've been going through. So not really sure. Hopefully the blood work will prove the latter because I'm super passionate about helping people stop smoking, being a smoker of 15 years. Good luck to you all!

Rebecca (author) from USA on December 29, 2014:

Sorry Phil, that sounds awful. I wish I would have had that problem, I started on 30mg didn't feel anything, then tapered down while quitting. I think vaping is a good alternative while quitting, but you never really know when to set it down since you don't stomp it out. Feel better, hope this hub helped you. :)

Phil on December 29, 2014:

So I got a vape pen for x-mas. Got a bottle with it @ 6mg. I didn't really feel it so I went back to the vape shop and got a bottle of 12mg. Puffed on it all day. Didn't realize it was nicotine poisoning until I woke up the next day feeling like crap. I finally ended up puking my guts out later in the evening...

Deb on October 04, 2014:

I haven't been able to figure out why I have felt so horrible..I have been smoking for about 40 years..lately I have had severe diarrhea, nausea ( haven't vomited) intermittent high blood pressure, severe sweating, tremors, and blurry vision. I have dramatically increased how much I smoke because of stress. Wow this article opened my eyes. Thanks

Kam on September 16, 2014:

Ecigs can be good but you have to be careful. I smoked cigarettes from the age of 14 to 32. I quit cigs 3 times during my life but I would always start them again. I tried ecigs in 2013 but i did not stick with them. I decided to only use ecigs starting in 2014. I bought real kits from online and I began to enjoy vapong very much. After a few months I begin to feel dizzy often so I went to the hospital. I had developed high blood pressure all of a sudden. I began to take blood pressure meds which all worked for a little while then I would have to switch medicine. I finally bought a home blood pressure tester so I could check my pressure any time. I was told that the blood pressure meds were not working because I did not have hypertension but was suffering from stress. The stress pills worked great but some times I would still get sick. My symptoms would always be light headed, dizzy, faint feeling, extremely weak, restlessness, rapid heart beat, rapid pulse, heart palpitations,not being able to sleep, and I even felt so bad 2 times I almost passed out thinking I was gonna have a stroke or heart attack. When I would get extremely sick I would not vape until after a few days I would feel better. I finally put together by using my blood pressure monitor that vaping was causing my problems. When I checked symptoms of nicotine poisoning and nicotine withdrawal they were exactly what I was experiencing. I like vaping but you have to be careful because there is no way of knowing how much nicotine you are getting especially by using variable voltage devices. I’m gonna try 0mg juice to find out if it is safe for me if not I will quit. I not bad mouthing vaping but everyone should be careful and have in mind to eventually decrease the nicotine in their juice until they make it to 0mg and check their blood pressure regularly, because if you consume to much nicotine accidentally you will have no warning all the terrible symptoms will hit you at once. Then the withdrawal symptoms will be just as bad ,and they all last from 1 day to a week in my experience. I love vaping but I will quit if I have to. I love everybody so all be safe and observant so we can make vaping 100 percent safe.

Alicia Alarco-Hernandez from Old Bridge, New Jersey on September 08, 2014:

Interesting, I don't use any from of nicotine but know others who do. Bad habit to break.

Richard on August 30, 2014:

If your using e-cigs to give up, I would slowly decrease the nicotine content until you get to 0mg. The other trick is to take those regular 4 minute breaks and use your e-cig then, instead of puffing away endlessly. Finally, be aware of different makes. If you have a bad experience of one, try another. Cheap is not always best.

Austin on July 31, 2014:

Having this issue right now. I c

Rebecca (author) from USA on July 27, 2014:

Tammy, I've been cigarette free for over a year... I noticed when I switched to the ecig, I never really knew when to "put it down" it's hard when it never burns out. I used it to often, my main issue was my fingers would get cold and numb. It was not very good. I'm almost off this junk completely, but still working on it. I hope the ecig didn't make you sick, but you know your body and it very well could have. Congrats to you on saying no more of any at all!!!

Tammy Lisa Carmen from USA on July 27, 2014:

I got rid of the e cig. I truly believe that this is what it was. I have tried it one last time post my last comment, and ended up in the bathroom again sick, vomiting, stomach cramps and it was awful. I do believe tho that I just lost count and puffed on it too many times. Still, it was so severe that I am done with it. No more smoking, and no more e smokes.

786 eggy on July 22, 2014:

very helpful i am getting rid of e cig i think i will try the hard way an quit smoking

Rebecca (author) from USA on July 16, 2014:

bg3300, you're probably right. Most people won't have a severe OD though. Usually just become very sick, which will pass. I wanted to put severe symptoms because of all the kids that have access to ecigs now, or ejuice. Thanks for your comment.

bg3300 on July 15, 2014:

You list 4 steps for a serious overdose. The last one being call 911. However, almost no one would be able to perform the first 3 steps, only emergency services or doctors. Most people are not going to be able to secure the airway or provide artificial ventilation. And people other than doctors should not be administering prescription drugs like Xanax and Valium nor do most people just have these on hand.

I think the only step for dealing with a severe overdose should be to call 911.

Lee on July 05, 2014:

@ Tammylisacarmen - I've also been using an E-Cig for the last month and this week I've been quite ill. Vomited a few times one night and since then I've just had no energy whatsoever, headaches & dizziness and just not been able to do anything the last 3 days. On a few occasions of refilling the E-Cig I've had some nicotine go onto my fingers which I washed immediately and sometimes when I've gone to take a puff on the e-cig there has been some liquid or something which I've sucked into my mouth.

I'm usually pretty fit and healthy and rarely get ill, and tracking down what I've done the past few weeks or what I've eaten and the e-cigs has been the only change....?

Tammy Lisa Carmen from USA on June 26, 2014:

Thanks for this article. It was helpful to me. I believe I had a slight overdose from e-cigarettes. I am just getting over it. Been vomiting, had the weakness, sweat etc. I didn't link it to the E-smokes at first, but the more I read up on it, I believe that this is what it was. I quit smoking about a month ago, and now I also laid down the Electronic ones.

Never Again on January 15, 2014:

Never experience such a head rush while standing trying different sample flavors from the vapor cigs. I swear I thought I was going to pass out and had a wave of panic, numbness and tingling, fast heart rate, altittle trouble breathing. I could only tell you it felt (from memory when I was a teen) of being really high on pot. Scared me soooo bad. Even had to call paramedics. I swear I really thought someone put pot or something into the flavor samples. Really, really scary!!!

Rebecca (author) from USA on July 23, 2013:

wow, I loved your feedback! I originally wrote this to tie into a quitting smoking hub, I learned more about nicotine in the process too. Thanks again!

Pauline Davenport from Isle of Man on July 22, 2013:

This fascinated me. At first I briefly glanced over your Hub Bishop 55, wrongly assuming it to be yet another rant on the perils of smoking - sorry for that.

I had no idea that the tobacco harvesters were affected in this way. I never even gave it a thought. It would be interesting to see if they smoked wouldn't it?

Being able to overdose on nicotine is novel too - something else new learned there, although looking back I guess I must have done in the past, having some of the symptoms you describe, either because of a cigarette or wearing a nicotine patch

Thanks for this- voted up and interesting. Brilliant stuff
